A little dicey to guarantee the fuel will draw and return equally. The newer common rail QSB Cummins move a lot of fuel even though they don't burn so much. A friend with the same HP as mine, leaves all valves open and has no trouble, but it is an older B Series Cummins. I generally run 15 hours or so then just switch tanks. Whatever works!
